I can't change the alias of my keystore or it won't recognize my app on the android market. It has to be the exact same keystore.
Under "Private Sign Key", it should be easy to add an additional field allowing an alias along with organization, password etc. When using the command line exe it allows you to enter the alias along with organization, first and last name, etc. If a command line approach is already used by b4a, it shouldn't be hard to implement.
Erel, you are very smart. I am sure you can figure it out. Furthermore this is the last denominator needed to allow porting existing apps to b4a. With this ability developers can to still be able to release an update to their app once it is converted to b4a.
